# UMRSF-TDDFT single-point excitation energies of butadiene (C4H6).
# BHHLYP / 6-31G* -- energy only.
#
# The single token "umrsf" carries what took four legacy keywords: a UHF
# (the "U") high-spin triplet reference, the unrestricted MRSF response, and
# the singlet target manifold.  Plain MRSF ("mrsf") differs only in using an
# ROHF reference; everything else is identical.
